LWM2M Server Connection Issue

i don’t know, but actually it won’t block your update as your can choose the second option to upgrade to another firmware and choose the version you want to update.

Could you send me a documentation that explains this second option to upgrade ?

I didn’t find it

If it’s the Upgrade to another firmware (Advanced) method, I’ve already try it and it didn’t work

yes, i mean the Upgrade to another firmware (Advanced) method

I used this option to upgrade to FW version from 4.5 to 4.8
